DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
With respects to FIGS. 1 to 4, a preferred embodiment of a wire-winding device for two kinds of cables according to the present invention is disclosed. The device includes a base 1, a first winding plate 2, a second winding plate 3, a first communication cable 4, a second communication cable 5 and a volute spring 6. The base 1 is hollow and includes a first half housing (or a lower cover) 11 and a second half housing (or an upper cover) 12 clamped or screwed together. The base 1 has a receiving cavity 13 formed therein for receiving the first winding plate 2, the second winding plate 3, the first communication cable 4, the second communication cable 5 and the volute spring 6. The base 1 has a first hole 14 through which the first communication cable 4 passes and a second hole 15 through which the second communication cable 5 penetrates. The base 1 has a pillar 16 that is hollow and disposed therein.
The first winding plate 2 is pivoted in the receiving cavity 13 of the base 1 and has a first plate body 21 and a hollow first winding shaft 22 disposed on a side of the first plate body 21. The first winding plate 2 pivots to an end of the pillar 16 via a first central shaft 23, so as to rotate the first winding plate 2 in the receiving cavity 13.
The second winding plate 3 is pivoted in the receiving cavity 13 of the base 1 and has a second plate body 31 and a hollow second winding shaft 32 disposed a side of the second plate body. The second winding plate 3 is disposed over the first winding plate 2. The second winding plate 3 pivots to an end of a first central shaft 23 via a second central shaft 33, so as to rotate the second winding plate 3 in the receiving cavity 13.
The first communication cable 4 has two ends connecting plugs 41 and 42. The first communication cable 4 is folded and winds about the first central shaft 22 of the first winding plate 2. Each of the two ends of the first communication cable 4 extends out of the base 1 via the first hole 14.
The second communication cable 5 has two ends connected to a plug 51 and an earphone 52. The second communication cable 5 is folded and winds about the second central shaft 32 of the second winding plate 5. Each of the two ends of the second communication cable 5 extends out of the base 1 via the second hole 15.
The volute spring 6 is connected between the first and second winding plates 2 and 3, and has first and second clamp ends 61, 62 locked on the first central shaft 22 of the first winding plate 2 and a clamping portion 34 disposed on a side of the second winding plate 3, so as to orientate the volute spring 6 between the winding plates 2 and 3. Thus, the first and second winding plates 2, 3 operate relatively and the volute spring 6 storages energy.
The wire-winding device according to the present invention can receive very long communication cables 4, 5 immediately and connect the plugs 41, 42 and 52 for information. Two ends of each communication cable 4, 5 are pulled by the volute spring 6 for keeping the drawing force from the cables intertwined.
In addition, the communication cables 4, 5 can avoid interfering with the user. The first plate body 21 of the first winding plate 2 has a plurality of slots 24 formed in a periphery thereof. A first reciprocal control device 7 is adjacent to the first winding plate 2 and includes a resilient swing member 71 free waving and a ratchet 72 free rotating. When the relationship between the resilient swing member 71, the ratchet 72 and the first slots 24 of the first winding plate 2 operates, the first communication cable 4 is capable of being fixed or reeled by pulling or releasing cyclically.
The second winding plate 3 has a second plate body 31. The second plate body has a plurality of second slots 35 formed at a peripheral thereof. A second reciprocal control device 8 is adjacent to the second winding plate 3.

The first tug bottom 18 has a first tug portion 181 abutting against to lock the first communication cable 4 when the first tug bottom 18 is moved towards the first hole 14. In contrast, when the first tug bottom 18 is moved away from the first hole 14, the first tug portion 181 is released so that the first communication cable 4 can be pulled. The first tug bottom 18 can control if the ends of the first communication cable 4 stretch.
The base 1 has a second tug bottom 19 arranged and sliding along a lateral side thereof and next to the second hole 15. The second tug bottom 19 has a second tug portion 191 abutting against to lock the second communication cable 5 when the second tug bottom 19 is moved towards the second hole 15. In contrast, when the second tug bottom 19 is moved away from the second hole 15, the second tug portion 191 is released so that the second communication cable 5 can be pulled. The second tug bottom 19 can control if the ends of the second communication cable 5 stretch.
Referring to FIG. 6, the plugs 41, 42 connected to two ends of the first communication cable 4 mate with each other for circling connection, so as to be hung on the neck of the user for easy carrying.
With respect to FIG. 7, the first winding plate 2 can pivot to the base 1 and the second winding plate 3 via the first central shaft 25 thereof. the central winding shaft 36 of the second winding plate 3 pivots to the base 1 and the first central shaft 25 of the first winding plate 2, so that the first winding plate 2 and the second winding plate 3 can be arranged and rotated inside the receiving cavity 13. The first and second communication cables 4, 5 are wound about the first and second central shafts 25, 36, respectively.
In addition, FIG. 8 shows the first central shaft 25′ of the first winding plate 2 pivoting to the base 1 and the second winding plate 2. The second central shaft 36′ of the second winding plate 3 pivots to the base 1 and the first central shaft 25′ of the first winding plate 2. Therefore, the first and second winding plates 2, 3 rotates inside the receiving cavity.
In accordance with FIG. 9, the first winding plate 2 pivots to the base 1 and the second winding plate 3 via the first central shaft 25′, and the second winding plate 3 pivots to the first central shaft 25′′ of the second winding plate 3 via the second central shaft 36′′. Therefore, the first and second winding plates 2, 3 rotate inside the receiving cavity 13, and the volute spring 6 is arranged on the second winding plate 3.
The two cables 4, 5 are arranged inside the device for various plugs and earphones for further broadly application.
